lMPBOVEMENT IN SODA-WATER DRAUGHT-TUBES.

Specification forming part of Letters Patent No. 124,892, dated March 26, 1872.

Specification describing an Improvement in Soda -Water Draught-Tubes, the invention of I DAVID FERGUs, of the city of Philadelphia,

in the State of Pennsylvania.

My invention relates to that part of the draught-tube which regulates the outflow of aerated water and consists, first, of a-peculiarly-formed perforated spindle. Second, of acombination of the spindle with apertures and a recess in the body of the tube, and a nozzle attached thereto, the whole being so constructed that, by a slight turn of the spindle, the aerated water is allowed'to escape, either as a concentrated sin gle jet for mixing the flavoring sirup, or in a divided or spray-like form.

In the drawing, Figure 1 represents a longitudinal vertical section of the draught-tube, spindle g being partly in elevation Fig. 2, a front elevation of the same; Fig. 3, a'transverse section on the line A B of Fig. 1.

c is the body of the draughttube d, the neck by which it is attached to the fountain or to a pipe leading tothe fountain; e, the stem of the draught-tube f, the nozzle attached to the stem 0. g is the spindle, which is expanded into a cone or frustum shape, and made hollow at its inner end, and perforated at h, i, and

- k, as shown, the conical part of the spindle being ground to fit its seat in the draught-tube. m, m and n are perforations through the stem of the draught-tube. 0 is a wheel fastened on the spindle g. p is a pin or stop attached to the spindle g. g is a recess, partially shown, formedin the body of the tube. It presents two shoulders, which, with the stop 0, limit the travel of the spindle g to about a half circle, or enough to bring the perforations h and 70 into line with the the perforations m and m or the perforation i into line with the perforation a, as required. A small spiral spring, not shown, is inserted at s between the'neck d and spindle g to keep the spindle inits place when the pressure of the aerated water is shut off. it is a cap to cover the recess q. 10 is a star or sight-mark, which is brought into line with the knob as on the draught-tube, as shown in Fig.

3, when the spindle g is turned into the posi tion required to stop the escape of aerated water.

The spindle g is shown in Fig. 1 in the position it holds when the perforations h and k are in line with the perforations m and m respectively, the stop 19 being then in contact with one shoulder of recess q, the water escaping through the perforations m and m and apertures m If the spindle is then turned until the stop 19 strikes the opposite shoulder of the recess q, the perforations t and n are brought into line and the aerated water escapes through the central aperture W.

I claim- The combination of the spindle g, the inner end of which is in the form of a hollow perforated cone or frustum, stop 10, recess q, wheel 0, body 0 of the draught-tube, perforations m and W, and nozzle f, all constructed and operating in the manner and for the purpose substantially as set forth.
